<p>Digest::Haval256 - A 5-round, 256-bit one-way hash function</p>

<h1 id="ABSTRACT">ABSTRACT</h1>

<p>Haval is a variable-length, variable-round one-way hash function.</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code>    use Digest::Haval256;

    $haval = new Digest::Haval256;
    $haval-&gt;add(LIST);
    $haval-&gt;addfile(*HANDLE);
    $haval-&gt;reset();

    $digest = $haval-&gt;digest();
    $digest = $haval-&gt;hexdigest();
    $digest = $haval-&gt;base64digest();
    
    $digest = $haval-&gt;hashsize();
    $digest = $haval-&gt;rounds();</code></pre>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>Haval is a variable-length, variable-round one-way hash function designed by Yuliang Zheng, Josef Pieprzyk, and Jennifer Seberry. The number of rounds can be 3, 4, or 5, while the hash length can be 128, 160, 192, 224, or 256 bits. Thus, there are a total of 15 different outputs. For better security, however, this module implements the 5-round, 256-bit output.</p>

<h2 id="Functions">Functions</h2>

<dl>

<dt id="hashsize()"><a id="hashsize"></a><b>hashsize()</b></dt>
<dd>

<p>Returns the size (in bits) of the hash (256, in this case)</p>

</dd>
<dt id="rounds()"><a id="rounds"></a><b>rounds()</b></dt>
<dd>

<p>Returns the number of rounds used (5, in this case)</p>

</dd>
<dt id="add(LIST)"><a id="add"></a><a id="add-LIST"></a><b>add(LIST)</b></dt>
<dd>

<p>Hashes a string or a list of strings</p>

</dd>
<dt id="addfile(*HANDLE)"><a id="addfile"></a><a id="addfile-HANDLE"></a><b>addfile(*HANDLE)</b></dt>
<dd>

<p>Hashes a file</p>

</dd>
<dt id="reset()"><a id="reset"></a><b>reset()</b></dt>
<dd>

<p>Re-initializes the hash state. Before calculating another digest, the hash state must be refreshed.</p>

</dd>
<dt id="digest()"><a id="digest"></a><b>digest()</b></dt>
<dd>

<p>Generates the hash output (a 32-byte binary string)</p>

</dd>
<dt id="hexdigest()"><a id="hexdigest"></a><b>hexdigest()</b></dt>
<dd>

<p>Generates a hexadecimal representation of the hash output</p>

</dd>
<dt id="base64digest()"><a id="base64digest"></a><b>base64digest()</b></dt>
<dd>

<p>Generates a base64 representation of the hash output. <b>MIME::Base64</b> must be installed first for this function to work.</p>

</dd>
